Scullery

This is intended to be a replacement for KitchenCI and kitchen-salt, focussing on testing SaltStack states using Vagrant and Pytest/Testinfra.

Installation

So far, a packaged installation is possible on openSUSE Tumbleweed:

$ zypper ar -f https://download.opensuse.org/repositories/home:/crameleon:/Scullery/openSUSE_Tumbleweed/home:crameleon:Scullery.repo
$ zypper in scullery

This will pull in vagrant, vagrant-libvirt, python3-vagrant, python3-pytest and python3-pytest-testinfra as dependencies.

Installation on Leap 15.4 is possible, however will currently cause dependency issues with the needed python-vagrant library.

It is possible to run scullery.py from a Git checkout of this repository if the dependencies are resolved manually.

Currently the script behaves purely as a console application and imports as a Python module are not supported.

Basic usage

scullery -h
usage: scullery [-h] [--debug] [--config CONFIG] [--env] --suite SUITE [--stop | --test | --status | --refresh] [--force-stop]

options:
  -h, --help       show this help message and exit
  --debug          Print extremely verbose output
  --config CONFIG  Specify the configuration file to use
  --env            Write environment file for direct use of Vagrant
  --suite SUITE    Specify the suite to run
  --stop           Stop running machines
  --test           Start machines and run tests
  --status         Get Vagrant deployment status
  --refresh        Re-sync files and re-run bootstrap scripts
  --force-stop     Invoke Vagrant destruction without having detected any running VM's

Command line examples

• To run a complete test suite:
  $ scullery --suite <name of suite> --test

• To create Vagrant VM’s without invoking the tests: $ scullery --suite <name of suite>

• To refresh the VM’s Salt files:
  $ scullery --suite <name of suite> --refresh

• To stop the VM’s and tidy up:
  $ scullery --suite <name of suite> --stop

Interacting with Vagrant

It is possible to directly interact with the Vagrant environment templated by Scullery. To do so, generate an environment file by adding --env to any command line call - for example:

$ scullery --suite <name of suite> --env

This will write a .scullery_env file to the current working directory. Export the environment variables in the file using your Shell, afterwards use vagrant like you normally would. Example for bash/sh:

$ set -a; . .scullery_env; set +a
$ vagrant ssh # or any other Vagrant command

Do not forget to unset the exported variables before you call Scullery with a different --suite!

Hacking

To test Scullery itself, call Pytest with your favourite arguments from the repository root:

$ pytest -v -rx -x tests/*.py

Make sure to not have any other Scullery based Vagrant VM’s running in the same Libvirt session and no SCULLERY_* or VAGRANT_* variables exported in your shell.

The complete test suite takes about 30 minutes to execute on an Intel i7-6820HQ CPU with SSHD storage. If you want to test only certain functionality, simply add -k <name of test function>.
